steady-state temperature will result in long warm up
times for the additional lamps.

3.3. Manual heating shut down (OFF)

The device heating is shut down by simultaneously pressing
the “UP” and “DOWN” buttons. "Off" appears on the display
(4). If the standby function is also active, the temperature is
reduced to 100°C (212°F). “Stb” appears on the display (4).

3.4. Automatic heating shut down (AUTO OFF function)

The auto off time for the heating shut down is displayed flas-
hing by pressing and holding (approx. 3 sec.) the HIGH
POWER button (2). The shut-down time can be adjusted in 5
minute steps in the range 5 - 600 min by pressing the “UP”
or “DOWN” button (5)(7). A setting of less than 5 min swit-
ches off the automatic heating shut-down and "OFF" appe-
ars on the display (4).
If the standby function is also active, the temperature is
reduced to 100°C (212°F). “Stb” appears on the display (4).

3.5. Operation using RS232 serial interface

When operated together with the WHA 3000P / WHA 3000V
hot air station, the WHP 3000 heating plate is controlled via
the RS232 serial interface (11). Here the heating plate is
used as a bottom heater for electronic assemblies and is
integrated into a 3-step temperature-time profile. When used
in automatic mode (Remote LED (1) illuminated) it is not pos-
sible to make any entries directly at the heating plate. Only
the switch over between the heating zones (9) remains acti-
ve. The temperature setting is made via the WHA 3000P /
WHA 3000V hot air station. When the program is not active,
the heating plate is switched off. "OFF" appears on the
display(4). If the standby function is also active, the tempera-
ture is reduced to 100°C (212°F). “Stb” appears on the
display (4).

3.6. STANDBY function

In standby mode the temperature is reduced to 100°C
(212°F) if a heating shut-down occurs (using OFF, AUTO OFF,
RS232). The standby mode is activated via a “Power-On
Routine”. For this purpose the device is first switched off at
the mains switch (6). Press the HIGH POWER button (9) and
switch on the device. Keep button pressed until the -- 1 -
appears on the display (4). When the “HIGH POWER” button
is released the setting is saved. The standby function is swit-
ched on. Use the same procedure for switching off. -- 0 -
appears on the display (4) (factory setting).

4. Operation with external Sensor

It is also possible to measure the control variable for the tem-
perature regulation using an external sensor. If an external
sensor is connected, the current temperature from the exter-
nal sensor is displayed and controlled instead of the
temperature of the heating lamps. The external sensor, an

insulated thermocouple type K, is connected to socket (10).
LED (3) on the display (4) illuminates.

Note:
The sensor must be adequately in contact with the
assembly or component for correct operation. When
working with the external sensor, the temperature set-
ting (setpoint) must be adjusted to suit the measuring
point.

6. Other power-on routines

°C / °F change over

For this purpose the device is first switched off at the mains
switch (6). Press DOWN button (7) and switch on the device.
Keep button pressed until the “°F” appears on the display (4).
When the “DOWN” button is released the setting is saved.
Use the same procedure for the change over to “°C”.

Resetting to the factory setting (FSE)

For this purpose the device is first switched off at the mains
switch (6). Press “UP” (5) + “DOWN” (7) + “HIGH POWER” (9)
button simultaneously and switch on the device. Keep but-
tons (5, 7, 9) pressed until "FSE" appears on the display (4).
When the buttons (5, 7, 9) are released the setting is saved.
